note 60344 added to function.array-diff

A small thing that caused me trouble today, wich I don't see listed on this page is that array_diff keeps the placing for the uniqe values, and removes the duplicated. This gives us empty fields in the array, wich caused me a lot of trouble. The solutions was simply to use array_merge() around the array_diff. For example: $array1 = array('blue', 'red', 'green'); $array2 = array('red'); array_diff($array1, $array2); Will give us: ------ Array ( [0] => red [1] => [2] => green ) But if we use: array_merge(array_diff($array1, $array2)); We will get: ------ Array ( [0] => red [1] => green ) ---- Manual Page -- http://www.php.net/manual/en/function.array-diff.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+60344 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+60344&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+60344&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+60344&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+60344&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+60344&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+60344&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+60344&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+60344&report=yes Search -- http://master.php.net/manage/user-notes.php
